Over Thanksgiving dinner I told one of the smartest people I know that I had just finished Manhunt, the true story of the attempt to capture the man who killed Abraham Lincoln. “Why did John Wilkes Booth kill Lincoln, anyway?” my friend asked. “Was he just crazy?”

I couldn’t have answered before I read Manhunt and, no doubt, many people still can’t. One of the chief virtues of this fascinating book is that it reminds us how little we know about some of the most familiar events in American history.

Lincoln scholar James L. Swanson hasn’t written a biography or a character study of Booth but a true-crime story about what happened between the actor’s escape from Ford’s Theatre after the assassination and his arrest at a barn in Virginia 12 days later. So he leaves unanswered many questions about Booth’s mental stability. Instead he casts the actor as a passionate white supremacist who saw Lincoln as a tyrant and was enraged by the president’s recent call for limited black suffrage. General Robert E. Lee had surrendered, but strong Confederate armies remained at large in parts of the South, and their leaders had not taken their cues from Lee. Booth may have been delusional enough to believe that, by killing Lincoln, he could affect what remained of the Civil War.

For all its absence of psychological insight, this story is rich in adventures worthy of Butch Cassidy and the Sundance Kid. Swanson follows Booth and an accomplice from Ford’s Theatre to the homes of Confederate sympathizers in Maryland and a pine thicket where they hid for five days until they believed they could safely cross the Potomac to Virginia in small boat under cover of darkness. And although he occasionally he describes thoughts by Booth that he appears to have had no way to know, he documents most of the story meticulously.

Manhunt came out just before Presidents’ Day, and some critics may omit it from holiday gift lists in favor of more recent titles. That’s too bad, because this book has much to offer adults and teenagers with a passion for U.S. History. Many of us learned from our teachers that after shooting Lincoln, Booth leaped onto the stage at Ford’s and shouted, “Sic semper tyrannis” – “Thus always to tyrants.” How many of us learned that he first said something else? Before leaving the president’s box, Booth shouted a single word: “Freedom!”

Best line: “John Wilkes Booth’s escape and disappearance unfolded as though scripted not by a master criminal, but by a master dramatist. Each additional day of Booth’s absence from the stage intensified the story’s dramatic arc.”

Worst line: Swanson describes what Booth was thinking just before his arrest in lines like: “Suicide? Never that shameful end, Booth vowed to himself. Richard III did not commit suicide, Macbeth did not die by his own hand, nor Brutus …” Swanson provides many endnotes, but none makes clear how he could have known this.
